// The magnifier's OSD, posted by Accessibility.stepZoom when a zoom keybind is
// pressed. An unmapped kind falls through iconFor to the kind's own name, and
// "zoom" is not an icon -- the OSD would draw the generic fallback glyph for
// the one shortcut whose whole job is telling somebody who cannot read the
// screen what the magnification now is.
// An empty bar is 1.00 ×, which is off rather than "barely magnified", so it
// gets the reset icon: the zoom-in glyph beside an empty bar would read as a
// magnifier that had stopped working.
